I did some extensive listening to the PM8004 and loved it. I have an old 1970s 2215B (15 watts, and it cooks nicely) that still serves me very well. I really love the Marantz sound and wish I could afford their reference line....the only reason I didn't get the 8004 is because I'm thinking more power and hence going with some Emotiva mono blocks. I'm really looking at buying my last system or, at least I'd like to be satisfied for a good long time. Maybe I'll consider a used PM8004 as a preamp.
